i think there has been other threads about this if you do a search. i am currently waiting to put mine in. i don't think i have the wire harness that i need. i have one line that goes to ground, one line that i think goes to the e brake, and one side of a 3 pronged (3 metal connecters, 2 are parallel and 1 is orthogonal to the other 2) wire harness. what does your wire harness look like and where did you get it? hopefully i will do this soon so if i figure it out i can post the results for you. oh, by the way, i have what i think is the older version, it is black with a little silvery triangular shaped part with an apexi logo on it in the bottom right corner, is that what you got?
